Grab the 3-D glasses and get ready for a new kind of home entertainment. TV manufacturers are joining Hollywood's mania for 3-D films, such as the fantasy adventure "Avatar," by bringing that technology in the living room. Those next-generation sets were a highlight of the four-day Consumer Electronics Show last week in Las Vegas, a yearly showcase of the latest gear for communication, learning, gaming and other amusements. More than 2,700 companies displayed products or services.

Attention-grabbing developments also included "smart TVs" that connect to the Internet, fancier smart phones, touch-screen cameras, 3-D gaming, in-car wireless Internet and tablet-size computers that present books, magazines and newspapers in print-style formats. For laptop users, a handy advance comes in a tiny shape -- thumbnail-size flash drives that are called "plug and stay" because they don't prevent computers from slipping into a carrying case.
Microsoft this year will introduce a motion-sensitive control system for the Xbox 360 that registers body movements without a physical controller -- a breakthrough that could make the Nintendo Wii seem like a dinosaur.

The biggest buzz was about TVs that make high-definition sets seem so last decade. Nearly every manufacturer will have an Internet-enabled model with WiFi wireless networking to let entertainment to flow from the home computer or laptop to the TV. Walt Disney Studios and others offer technologies that let consumers pay once for a movie or show and then watch it on multiple devices, such as smart phones or wireless players. "I really see it as almost like the plasma that flows through the devices, from one to another," said Bob Chapek, a Disney executive. "Any device that's not connected is at risk of becoming obsolete."
At their Las Vegas booths, LG and Panasonic demonstrated sets that could accept a webcam plug-in to serve as video phones for the Skype Internet calling service.
